IMPROVEM IIENTV INDUMPING-WAGONS.

Specification forming part of Letters Patent No. 222,392, dated December9, 1879 application filed v September 29, 1879. l I

To all whom it may concern: Be it known that I, WILLIAM EvANs, of thecity and county of Philadelphia, in the State of Pennsylvania, haveinvented a new and useful Improvement in Dumping-Wagons,

of which the following-is a specification.

I My invention mainly consists in the combination of toothed sectors andpinions with the frame and body of a dumping-wagon in such a manner thatby turning the crank-shaft of the pinions for operating the sectors,which are hinged or pivoted to the frame and body, the latter is broughtinto an inclined position for dumping itscontents or discharging them bymeans of a chute, the position of the.

. body being regulated by means of a roller and cords, or chainsconnected at one end with the roller and at the other end with the body.v

In the accompanying drawings, which make a part of this specification,Figure 1 is a side elevation of a dumping-wagon with my improvementsattached. Fig.2 is a front ele-. vation of the same. Fig. 3, Sheet No.2, is a A perspective view, of the swinging gate M.

Fig. 4 is a side view of one of the sectors 0 on an enlarged scale, inconnection with one end of the rods E. Fig. 5 is an edge viewof thesame.

Like letters of reference in all the figures indicate the same parts. I

A is the bed-frame of alwagon, and B the body. I I I O G are toothedsectors, which have hubs In, that are adapted to oscillate on bearings'bb, which, in the present case, are the ends of the 1 axle-bed D, thesaid ends being confined in the lugs c of the frame A. 1

T The sectors at their periphery have lugs d,

I which have a permanent 1 connection with the ends of the cross-rod E,which is adapted to turn freely in the lugs e e on the bottom of thebody B.

G.1S a rotating shaft, having a crank, f. It has its hearings in lugs ca of the frame A, and is provided withpinions H H, and

hence by turning the shaft in the direction of the arrow g the action ofthe pinions upon the sectors move them in the direction of the an row h,whereby the body B is tilted intoa po sition for dumping or dischargingits contents through a chute into a cellar. The body is shownin thelatter position in Fig. 1 by full lines, andin the former position bydotted. lines.

It is also shown in its closed by dotted lines;

I have represented the sectors and pinions position connected by meansof spur-gearing; but, if desired, worm: gearing may be used instead ofit.

The rear end of the body B beyond its pivotal connect-ion with thesectors 0 G is purposely heavierthan the front end, to cause it Theposition is regulated by means to tilt. of the roller I and cords orchains J J, one

end of which is connected with the roller and r the other end with thebody. The rolleris; provided with the ratchet-wheel K.

L is a pawl which is hung to the .frame A and connectswith theratchet-wheel.

By means of these devices, in combination.

with the sectors and pinions above described,

the position of the body is regulated at any desired angle, or in anelevated horizontal position, the body being free to turn into either ahorizontal or angular elevated position by means of its pivotalconnection with the upper corners of the sectors 0 O, as abovedescribed.

Instead of the ratchet-wheel and paw], aworm-wheel gearing or otherdevice may be used for holding the roller I in its adjusted position.

Mis a gate. (Shown in detailin Fig. 3.) It

has an oscillatory connection with therear end of the wagon by means ofthe pivots i 6, whereby it is adapted to be used for the dumpingoperation; but in order that a coalch'ute may be used when desired fordischargingthe contents of the wagon into a cellar, I

provide the gate with the chute mouth N, which has a sliding gate, 0,for opening and closing it. I

I claim as my invention 1. The combination of the shaft G,.havi;ngpinions H H and the sectors 0 G, with'the frame A and body B, havinglugs e c, the body being pivoted to the sectors by means of said lugsand the cross-rod E, substantially in the ratchet-wheel K and pawl L, orother convenmauner and for the purpose set forth. ient device,substantially as set forth.

2. The combination of the roller I and T cords or chains J J with theframe A, body WILLIAM EVABS B, sectors 0 U, and pinions H H, forregulat- Witnesses: ing the position of the body, the roller beingTHOMAS J. BEWLEY, held in its adjusted position by means of the STEPHENUSTICK.
